Re: This evaluate thing always stumps me...
On a more "personal style" note, I generally do a cfparam on all my form variables and then loop over the form structure and trim() all the values. I then do not have to check for existence or trim when checking length.

Re: This evaluate thing always stumps me...
Adding to Charlie's advice...
structKeyExists() is faster than isDefined() and I have not found a case
where it couldn't be used instead. It can be used on local values by
checking the variables scope: structKeyExists(variables, "localVarName")

You don't need to use Evaluate() to perform that isDefined check. Simply use: If you need to get the reference to that variable, use array notation on your Form struct: Form['grp_sort_#myIDX#'] Jonathon ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:296991 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

That should do it, and without the need for Evaluate.

Get rid of the Evaluate statement.
This: evaluate("form.grp_sort_#myIDX#")
Becomes this: FORM["grp_sort_#myIDX#"]
or this: FORM["grp_sort_" & myIDX]

Since CF 4, you don't really need to do this much work. And beside that,
IsDefined automatically evaluates its argument.
